$PEGIFEZCATION forming part of Letters Patent No. 532,762, dated January22, 1 895.

Application filed April 9, 1894. Serial No. 506,867. (No model.)

To all whom, it may concern:

Beit known that I, THOMAS OARNEY,a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented a certain new and useful Improvement in Cash RegistersandIndicators, of which the following is a description, reference being hadto the accompanying drawings, forming part of this specification.

My invention relates more particularly to certain improvements upon themachine shown and described in Letters Patent of the United States Nos.497,860 and 497,861, granted me May 23, 1893, but the utility of itsseveral features is not restricted to such machine.

The novelty of the invention consists in certain new constructions,arrangements, combinations and modes of operation of the several parts,which will be hereinafter set forth and particularly pointed out in theclaims.

In the accompanying drawings Figure 1 represents a top plan view of themachine removed from its casing; Fig. 2, a vertical sectionapproximately on the line 22 of Fig. 1, looking toward the left; Fig. 3,a vertical section approximately on the line 33 of Fig. 1, lookingtoward the right; Fig. 4, an enlarged perspective view of theregistering wheels and associated devices; and Fig. 5 an enlarged detailof one end of the slotted guard plate.

The same letters of reference are used to indicate identical parts inall the figures.

Reference may be had to my aforesaid prior patents for a detaileddescription of the general construction and mode of operation of themachine, so that a brief description of them will be suflicient here.

The operating keys consist of levers A fulcrumed on a fixed horizontalrod B, passing through slots in a guide plate O at the front of thecasing, passing at their rear ends through a vertically slotted guideplate D and resting upon a cross piece E of the framework.

The indicators of the machine consist of tablets F carried by verticalrods G resting at the lower ends upon the rear ends of the key levers.

The operating keys are divided into sepaa vibrating or swingingregistering frame,

there being three of such frames, L M N, mounted upon a rock-shaft Ojournaled at its opposite ends in bracket supports P upon the sideframes of the machine, Fig. 1. The frames L M are loose upon the shaft 0and the frame N is fast upon it. The frame L has fast upon its left handend an upwardly and forwardly projecting gear toothed segment Q, whilefast upon the right hand end of the frame M, adjacent the segment Q, isa similar segment R, and at the left of the latter and fast upon therock-shaft O is a third similar segment S, Fig. 3. These segments areadapted to be engaged with and disengaged from the driving pinions T ofthe first, second and third wheelsof a totalizing register U hereinaftermore particularly referred to.

Each of the registering frames L M N has rigidly secured in its rearside a transverse rod V parallel with the shaft 0 upon whichv the framesare mounted. Each of these rods V is adapted to co-operate with a seriesof graduated lifters l/V of the corresponding set of group of keys.These lifters consist of plates connected attheirlower endsto thekeysnear the rear ends of the latter, provided in their forward edges withrecesses X forming fingers Y, and upon their rear edges adjacent suchrecesses and fingers with rounded shoulders or knuckles Z, Figs. 2 and3. The recesses X and fingers Y of the different lifters in each groupare arranged at different dis tances from the rodV of the registeringframe with which they co-operate, the arrangement and adjustment of theparts being such, as explained in my prior patents, that the full strokeof any key in a group Will cause its lifter to move the correspondingregistering frame a distance proportionate to the value represented bysuch key. The fingers Y upon the lifters normally stand beneath theircooperating rods V, so that when the lifter is moved upward its fingerand recess will engage the rod and rock the registering frame, but forthe purpose of throwing the upper end of the lifter slightly forward andfully engaging its recess X with the rod V each lifter is provided witha shoulder Z upon its rear edge, which shoulder cooperates with thelower forward corner of a fixed cross bar A of the framework, theengagement of the shoulder Z with such bar serving to throw the upperend of the lifter slightly forward at the moment its recess X engagesthe rod V and to thereby cause the lifter to clutch the rod and becomelocked to it, so that any independent movement of them during thefurther upward movement of the parts is prevented. The rear edge of thelifter below the shoulder Z is so curved that the engagement of the barA with it after the shoulder Z has passed above the lower edge of saidbar will holdthe lifter locked to the rod V during the further upwardmovement of the parts. In this manner at the moment an operated keybegins to move the registering frame it becomes connected to said frameso that neither can move independently of the other, and the exactportion of the movement of the key desired is thus transmitted to theregistering frame and any excess of movement of the latter prevented.For the purpose of positively arresting the parts at the end of thepositive strokes of the keys and upward movement of the lifters thelatter are provided upon their rear edges with shoulders B having abruptupper surfaces, which shoulders contact with the lower edge of the crossbar A at the end of the upward movement of the lifters.

In my prior machine the lifters IV were pivoted at their lower endsdirectly to the sides of the key levers and there was noindependentmovementofthem. 'lhesegments of the registering frames areengaged with the pinions of the registers at the beginning of thepositive strokes of the key-levers and disengaged from them at thebeginning of the return or negative strokes of such levers, ashereinafter described, and where the registering frames begin theirreturn movement at the same time that the keys begin theirs, as wasnecessarily the casein myprior machine where the lifters were directlypivoted to the key-levers, some considerable nicety of adjustment isnecessary to insure the disengagement of the segments from the registersbefore the segments and registering frames begin their backward movementand thereby prevent dragging of the segments over the pinions.

In mypresent machine I have connected the lifters to the key-levers byslot and pin connections which will permit slight move ment of thelevers independently of the lifters and registering frames at thebeginning of both the positive and negative strokes of ssavee suchlevers. Thus, as will be seen, when the front end of a key-lever isdepressed the pin upon the side of its rear end will have to travelupward through the length of the slot in the corresponding lifterbeforeit will begin to move the latter, and at the beginning of the returnstroke of the lever the pin will move downward through the length ofsuch slot before it will pull the lifter downward. Now, as hereinafterdescribed, the pinions of the registers are moved into engagement withthe segments of the registering frames at the beginning of the positivestrokes of the keys and moved out of engagement therewith at thebeginning of their negative strokes, and it therefore results from thisloose connection of the lifters with the key-levers that the returnstroke of the operated key will be sufficiently advanced to disengagethe registering pinions from the segments before the latter are returnedto normal position.

While the slot and pin connections of the lifters with the keyleverspermit slight independent movement of the lifters, yet the provision ofthe shoulders 13 upon the rear sides of the lifters and the contact ofthose shoulders with the lower edge of the cross bar A at the end of thepositive strokes of the keylevers will prevent any overthrow andexcessive movement of the lifters and registering frames, as mightotherwise be the case. In the present machine, also, the lower portionof the rear side of the cross bar of each registering frame is curvedconcentrically to the shaft V and the fingers Y on the lifters are soshaped as to [it snugly in the space between the rod V and such curvedsurface, with the result that when a lifter is moved into engagementwith its registering frame it will become securely connected thereto andplay between them be prevented.

The registering frames and their segments are yieldingly held in andreturned to their normal positions by springs 0 connected at their lowerends to the segments and at their upper ends to the forward edge of aplate D secured to and projecting upwardly and forwardly from the crossbar A, Fig.

Journaled in the framework of the machine and extending transverselyacross the same beneath and parallel with the shaft 0 is a rotary shaftE. Ovcrlying and resting upon the upper sides of the keys beneath thisshaft is a heavy cross bar F hung at the opposite ends of its forwardedge to the side frames of the machine at G. This bar is provided alongits rear side with a flange II adapted to cooperaie with slotted lugs orhooks I upon the key-levers, to couple the latter to said bar, in a wellknown manner. Interposed between the bar F and the rotary shaft E is amechanical movement, illustrated 'and described in detail in myaforesaid prior patents, and not here shown, by which the reciprocatingmovements or vibrations of the bar F under the operations of the keylevers are transmitted to and converted into rotary motion ward a halfrevolution during the positive stroke of a key and lifting of the bar F,and

another half revolution during the negative stroke of the key and returnof the bar F.

The totalizing register U, Fig. 1, is supported in a rocking frame J,Figs. 1 and 4, mounted upon a fixed rod K supported in the framework. Bymeans of cams upon the rotary shaft E and connections between the sameand the rocking frame J, illustrated and described in detail in my priorpatents, said frame is rocked forward and backward at each completeoperation of the machine, to throw the driving pinions T of theregistering wheels into and out of mesh with the segments upon theregistering frames. The adjustment of the parts is such, as described inthe aforesaid patents, that the frame J is rocked backwardly and thepinions engaged with the segments at the beginning of the positivestroke of the operated key, and rocked forward, to disengage the pinionsand segments, at the beginning of the return or negative stroke of suchkey. In this mannerthe movements of the registering frames and segmentsin one direction are imparted to the registering wheels, while thelatter are not affected by the movement of the segments and frames inthe opposite direction.

In my aforesaid patents the transfers between the several registeringwheels were effected by means of transfer pawls, the complete revolutionof any wheel in the series operating to set the transfer pawl belongingto the next higher wheel, so that when said pawl was actuated suchhigher wheel would be turned by it to register the transfer. To insurethe proper transfers at all times it was necessary to actuate thesepawls in succession from the lower to the higher denominations, so thatthe pawl belonging to a given wheel would not be actuated until the nextlower wheel in the series had been turned as far as might be requiredboth by the number to be added upon it by the direct operation of a keyand any transfer to be effected to it from a preceding wheel. Inasmuchas in a register employing six wheels it was necessary to employ fivetransfer pawls, and inasmuch as such pawls had to be actuated insuccession during the negative or non-registering strokes of the keys,it was found extremely difficult to insure their accurate operationunder all circumstances in such a limited period of time as thatoccupied by the return stroke of the keys in the ordinary operation ofthe machine. To overcome this difficulty I have in some machinesarranged the cams upon the rotary shaft to actuate the pawls for two orthree of the highest wheels during the positive strokes of the keys,under which arrangement the transfers between the lower wheels would beeffected at the operation of the machine at which said wheels wereactuated, but any transfers from them to the higher wheels, or betweenthe latter, would not be effected until the next succeeding operation ofthe machine. Thus, the register at the end of any operation would notnecessarily exhibit the full amount which had been added upon themachine, and assurance that it did exhibit such full amount could be hadonly by operating one of the blank or special keys of the machine tothereby make certain that all transfers were effected. I have overcomeall of these difficulties and objections in my present machine byproviding transfer pawls for only the second and third wheels in theseries, and effecting the transfers between the remaining wheels bymeans of transfer gears or pinions meshing with similar gears upon thesides of the respective wheels. Thus, as seen in Fig. 4 there areprovided two transfer pawls L M adapted to cooperate with ratchets uponthe second and third registering wheels, in the manner illustrated anddescribed in my prior patents, while between the third and fourth wheelis a transfer gear N and notched locking disk 0, the former meshing witha gear P upon the right side of the fourth wheel and the latterco-operating with the notched hub of the third wheel to lock the gear Nfrom movement except when the third wheel completes a revolution.Projecting from the hub of the third wheel is a tooth Q adapted toengage the gear N at each complete revolution of the third wheel andturn said gear and consequently the fourth wheel one-tenth of arevolution and thereby add a unit upon said fourth wheel. Similartransfer devices are interposed between the fourth and fifth and fifthand sixth wheels. It is an easy matter to actuate the transfer pawls forthe secend and third wheels in succession during the negative stroke ofthe operated'key or keys, so that the transfers to those wheels willalways be properly effected, and inasmuch as the transfers between thehigher wheels will always be effected by means of the transfer gears andassociated devices, regardless of the length of time consumed in theoperation of the machine, it will be seen that all of the transfers arerendered sure and the register caused to exhibit at the end of eachoperation the total amount added upon the machine.

I am of course aware that trains of registering wheels provided withtransfer gears and locking disks such as those I employ are old, but Iam not aware of any instance in which transfer pawls actuated insuccession have been employed for effecting the transfers between thelower wheels of the series and the other form of transfer devicesdescribed between the higher wheels of the same series.

The next feature of my invention relates to novel means for locking themachine from operation during the time the registering wheels are beingreturned to Zero. As shown and described in my prior patents theregistering wheels are mounted upon a rotary shaft B, Fig. 4 and haveinterposed between them and the shaft suitable devices to cause theshaft to pick up the wheels and carry them with it when turned in onedirection. The shaft R has fast upon its right hand end a beveled pinionS meshing with a corre sponding pinion T upon a vertical resetting shaftU having fast upon its upper end a milled thumb-piece V by which it maybe turned to rotate the shaft R and pick up the registering wheels andcarry them to initial position. Fast upon the left hand end of the shaftIt Fig. 3 is a notched disk V7 with which co-operates a spring-pressedplate or lever X pivoted to the frame J at Y and having a lowerrearwardly extending arm Z which fits in a notch in a rocking plate A?pivoted to the framework at B and projecting at its rear endovertherotaryshaftE. Fastuponsaidshaft in line with the plate A is adisk G provided with a notch which in the normal position of the partsrests immediately beneath the rear e nd of the plate A \Vhenever theshaft R is rotated by turning the thumb piece V, to reset theregistering wheels, the movement of the disk W upon the left hand end ofthe shaft R will tilt the lever X upward as the notch in the disk iscarried away form said lever, and this tilting of the lever will tiltthe plate A and throw its rear end downward into the notch in thelocking disk 0 upon the shaft E and thereby lock said shaft frommovement and consequently prevent an operation of any of the keys untilthe resetting shaft R reaches normal position and the notch in the diskis brought into engagement with the lever X again, whereupon a springacting upon thelever X will restore the parts to the positions shown inthe drawings. In this manner the machine is locked during the operationof resetting the registering wheels, while, conversely, the resettingshaft R is locked from operation except when the operating keys androtary shaft E are in their normal position of rest, for when the shaftE and the locking disk 0 are turned from normal position by theoperation or partial operation of any key the surface of the disk 0 willride under the rear end of the plate A against or adjacent the same, andprevent any tilting of the latter and consequently lock the lever X inthe position shown in the drawings, with its upper rear end engaged withthe notch in the disk W fast upon the shaft R. Inasmuch as the shaft Itcannot be turned without rocking the lever X as the notch in the disk XVis carried from under said lever, it will be seen that the shaft Rcannot be turned to reset the wheels until the operating keys and shaftE are restored to normal position and the notch in the disk 0 broughtunder the end of the plate A The machine is provided with the usualmoney drawer D and this drawer, when closed, is locked by the engagementwith its rear wall of the downwardly bent rear end of a locking lever Ewhich is pivoted at its front end to a support upon the top of thedrawer compartment at F About midway of its length this lever isprovided with an upwardly extending arm G whose upper end carries ananti-friction roller standing in the path of a cam I'l fast upon therotary shaft E (dotted lines, Fig. 3). At each operation of any one ofthe keys and complete rotation of the shaft E the cam H will throw theupper end of the arm G forward and thereby lift the rear end of thelocking lever E and release the drawer.

For the purpose of preventing operation of the keys while the moneydrawerstands open there is provided a backwardly and forwardly slidinglocking plate I mounted in suitable guides upon the top of the drawercompartment. This plate is provided upon its upper edge with a slottedlug or hook J similar to the lugs 1 upon the keys, which lug when theplate is in its forward position catches over the flange 11 upon therear edge of the vibrating cross-bar F and locks said bar, andconsequently the key levers, from movement. A spring K connected to theplate I tends to hold the latter in its forward looking position, butthe plate has upon its under side a rearwardly projecting arm L whosedownwardly bent rear end stands in the path of a plate upon the rearwall of the drawer, so that when the drawer is closed the plate I willbe slid rearwardly and maintained out of locking position.

When a key is operated and the drawer released and the cross bar Flifted the locking plate I will be pulled forward slightly to its limitof movement, and when the key is released and the bar F restored tonormal position its flange H will press the plate 1' backward and catchunder its hook, thereby looking the barand keys until the drawer isclosed.

For the purpose of throwing this locking device out of operation at willthere is provided a vertical rock-shaft M having fast upon its lower enda plate N which when the rod is turned to the position shown in Fig. 3engages the front end of the locking plate I and forces the latterrearward and maintains it out of locking position. Then the shaft M isturned in the opposite direction and the plate N carried away from theplate I the latter will be thrown into operative position by its springK A milled thumb-piece O is secured upon the upper end of the shaft Mfor turning it.

Heretofore in machines of this class the operating keys and parts movedby them have been reset to normal position by the gravity of partslifted by the keys or the action of springs put under tension by them.To insure the prompt resetting of the keys and other parts it has oftenbeen found necessary to employ strong springs or make the gravitatingparts of considerable weight, and the work of putting these springsunder tension or lifting the gravitating parts was added to the otherduties of the keys. In my present machine I employ a strong resettingspring for the keys and parts moved by them, and

IIC

thus insure their prompt return to normal position, but relieve the keysentirely of the work of putting the spring under tension by providingmeans for putting it under tension by the closing of the money drawer,maintaining it under tension by the drawer while the latter is locked inits closed position, and releasing it and permitting it to act upon theparts to be reset when the drawer is released and opened. Theapplication of this resetting spring is shown in Fig. 2. Pivot-ed to theleft hand side plate of the framework at p is a rearwardly anddownwardly curved arm Q carrying at its lower end an anti-frictionroller R standing in the path of the rear wall of the drawer D A strongspring S connected at its rear end to said arm and at its forward end toa front crossbar of the framework tends to pull said arm forward, butwhen the drawer is in closed position it holds the arm in the positionshown in the drawings. In such position the drawer latch bears theentire stress of the spring and it has no action upon the key levers orthe cross bar F overlying them. When, however, any key is operated andthe crossbar F lifted the spring L will pull the arm Q downward andforward as soon as the drawer is released by its latch and cause it toengage a stud or projection T upon the left hand end of the cross bar F(said stud being preferably surrounded by an anti-friction collar)thereby applying the full force of the spring to the cross barFand'operated key or keys and causing it to assist their gravity inpromptly restoring them to normal position. When they reach suchposition the arm Q will rest against the projection T upon the end ofthe bar F until the drawer is closed and the arm moved by it to theposition shown in the drawings. The portion of the rear wall of thedrawer which engages the frictionroller R upon the lower end of the armis preferably cut away or inclined as shown by the dotted lines, tofacilitate the resetting of the arm. In this instance the spring S isthe only spring shown for automatically opening the drawer when releasedby its latch, but another spring for that purpose may be employed ifdesired. It will be understood that the drawer is not released, topermit the spring S to act, until the operated key has completed itspositive stroke. This will be apparent from the position of the cam H inFig. 3, where it will be seen that it will not move the drawer-latch andrelease the drawer until after the shaft E has completed a halfrevolution and consequentlynot until after the operated key hascompleted its positive stroke.

From theforegoing description it will be seen that a resetting spring ofany desired strength may be employed and the entire work of placing itunder tension be imposed upon the drawer and the operating keys berelieved of all duty in that respect. So far as I am aware I am thefirst in the art to providea resetting spring for the keys arranged tobe put under tension by the closing of the money-drawer, and myinvention in this respect is therefore limited only by the terms of therespective claims in which it is expressed.

Inasmuch as the parts just described would remain inoperative if thedrawer were held in its closed position by hand during the entireoperation of the machine, I have provided means for preventingmanipulation of the machine in that manner. To that end I have mountedby slots and screws upon the side of the arm Q asliding plate U providedwith a downwardly projecting arm V having in its rear edge near itsjunction with the body of the plate a rounded recess WV A coiled springX connected at one end to the arm Q and at the other to the plate Utends to pull the latter rearward, audit is maintained in forwardposition against the stress of such spring by the engagement of thelower end of its arm V with a projection T upon the end of the bar F.lVhen, however, the bar F is lifted by the operation of a key until itsprojection T comes opposite the recess W the spring X will slide theplate U rearward and engage the recess W with the projection T andthereby catch and support the bar F. Inasmuch as the flange H upon therear edge of the bar operates to lock all of the unoperated keys duringthe time the bar is displaced from normal position, in the well knownmanner, it follows that until the drawer is released and opened and thespring S allowed to pull the arm Q downward and forward and reset theparts no other key in the machine can be operated, so that the machinebecomes locked from further use until the drawer is opened. Attheresetting of the arm Q to the position shown in the drawings, after thedrawer has been opened and when it is again closed, the recess W in theplate U will clear the projection T upon the end of the bar F and permitthe latter to remain at rest while the arm Q} and plate U resume thepositions shown. For the purpose of preventing the insertion of Wires orinstruments of any kind through the slots in the front plate 0 of thecasing there is arranged immediately behind said plate, in suitablesupports, a laterally sliding plate Y provided with a series of verticalslots, one for each key lever, Fig. 5. lVhen this plate is in its normalleft hand position its slots do not register with the slots in the plate0, so that the plate Y serves to close the slots in the plate 0. Thecross bar F heretofore described has secured to it near its right handend a forwardly extending arm or rod Z Fig. 3, whose front end fits in acam groove upon the rear side of the plate Y Fig. 5. WVhen any one ofthe key levers is depressed and the bar F thereby lifted the downwardmovement of the front end of the rod. Z will force the plate Y to theright and cause its slots to register with those in the plate 0, andthereby permit depression of the operated key. Upon the return of theparts to normal position the upward movement of Fit ii se /c2 the frontend of the rod Z in the cam groove will move the plate Y to the leftagain and close the slots in the plate C.

Loosely mounted upon a shaft A suitably supported upon the framework,Figs. 1 and 2, are three registers B 0 D The register B is employed toregister the total number of operations of the machine. It is actuatedby a pawl E pivoted in the upper end of a bent lever F hung upon a rod Gand extending at its rear end beneath the front end of an arm H rigidlysecured to and projecting forward from the bar F. When the latter bar islifted by the operation of any key in the machine the downward movementof the front end of the arm H will tilt the lever F and cause the pawl Eto advance the register B one number. The register C is actuated by thepawl l suitably connected to and operated by the special key I, topreserve a register of the total number of operations of the latter key,while the register D is actuated by a pawlJ connected to and operated bythe special key J, for the same purpose. Suitable devices are interposedbetween the wheels of these registers and the red A upon which they aremounted to cause the latter to pick up the wheels and carry them to Zerowhen it is turned in one direction, and the rod has fast upon its righthand end a milled thumb piece K for turning it for that purpose. Nearthe right hand side of the machine, in line with the registersjustdescribed, are two more similar registers L M actuated by the specialkeys H and K respectively, to preserve a register of the number ofoperations of those keys. The key H is connected by a link N Fig. 3, tothe lower end of a curved arm 0 which is rigidly secured at its upperend to a rock-shaft P Fig. 1, which shafthas fast upon it adjacent theregister L an upwardly extending arm Q in which is pivoted the pawl Rwhich actuates the register L The pawl R which actuates the register Mis similarly connected with the special key K.
